The inner member ot the regulator construction is placed inside the outer member with its rib l'seated in the groove onv the inner side ot'the rib 7 ot the cover member, the operating 'handle is then 'placed over the 'rib 7, its end covering th'eopening at 9, and the 'openings 24 and 19 are yp'os'iftio'i'ied in alinement. When so positioned, the 'tl-anges 25 and linger engaging ears 26 extend in- '\'vardly, the ears extending alongside 'the sides ot the ontcr cover member. A connecting member 'ZT ormedflrom liat metal is passed through 'the alincd slots, at outer end having 'a Wider head 2S which bears against the inner lend of the lia'ndle. An opening '29 is made through the inner end ol member 27.y A coiled spring 30 placed around the member 27, at o'n'e end seating in the groove of rib 16, and afcotter pi'n is passed through opening 29 against which. theouterfend ol the spring beafrs. This com-1 4pletes the assembly of the regulator construction and it is ready for operation, it being understood that the chain 15 is 'connected to the inner Ioperating member before assembly it desired or it may be attached later.

This construction of regulator has the inner member bearing against the outer member th'rugh the iorce ot spring press-ure ex erted by the spring 30, Where the ribs 7 and l.ldh'ave'a contact engagement, and the tric-y tion` ot such engagement holds the parte yie'l'dingly in. position to which they may be moved. The-inner andnuter member, the and connecting member 2T are all easily prodiiced in quz'lntity by punch 'i' ress operations, whilethe sjn'ingnnd rot-ter pin are produced by makers thereof by automatic machinery and can vbe bought in quantity at low price. rIi'his lmakes thefregulfator construction one veryfeconoinical to manu-- l"facture, 'as the assembly is vvery simple.
